When you are over a context or cost budget and the prompt itself is not negotiable.
This prompt plus context totals [N] tokens: [paste]. Cut it to [target] tokens by trimming redundancy in the context, not the instructions. Show the trimmed version and what you removed.
Anything in square brackets is meant to be replaced. The builder turns those into fields you can type into.
Tired of re-pasting the same context into every new chat? That is what the Unimatrix MCP server is for.
